SPECIFICATION forming part of Leu-.ers Patent No. 517,814, este@ April 3,1894.

Application tiled J' uly 6,1891. Renewed December 9, 1893. Serial No. 493,450. (No model.) Patented in Canada April 9,1889,

I. A No.31,o6e.

.To all whom. it may concern:

Beit known that I, RICHARD H. OAssWELL, a subject of the Queen of Great Britain, and a resident of Ingersoll, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Milk-Puriers, (for which I have obtained a patent in Canada, No. 31,069, bearing date April 9, 1889,) of which the following is a full, clear, and exact Io description.

My invention has for its object to improve the construction of milk purifiers, whereby in the process of straining and aerating, the globules are prevented from being crushed and broken by concussion while passing from the strainer into the can in which the milk is transported.

My invention consists of an attachment to milk cans, comprising a straining vessel, funzo nel-shapedat the bottom, and having an exterior neck provided with a disk suspended below the outlet, to spread the milk in an an-V nular thin lm before falling into the can, and a deector sleeved on the neck, to direct the ilow into the can, when exposed to the wind. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1. represents a vertical section of my 3o improved strainer and aerator for the purification of milk. Fig. 2. is a side elevation of same.

A, designates the straining vessel, into which the milk to be purified is poured, and 3 5 said strainer has a funnel-shaped bottom.

B, is a perforated strainer, covering the outlet within the vessel.

C, is a tubular neck, screwing onto a collar secured to the exterior bottom of the vessel 4o at the outlet, and from said neck is suspended a disk, D, offset from the lower end of the neck, and secured xedly by a U-shaped wire,

E, fastened to the inside of the neck, or other suitable manner, so as to leave a clear opening between the lower end of the neck and face of the disk, whereby the milk will flow into the can below in an annular thin lm andby contact with the atmosphere aerated and deodorized.

Heretofore the practice has been to allow 5o the milk to escape from the straining vessel through perforations, in small streams, and such practice has been found injurious, which is avoided lby my invention. The straining vessel, A, is provided with legs, F, having feet, 5 5 Cr, bent to t on the edge of the milk can, J, in the usual manner. f

H, is an adjustable dellector, sleeved on neck, C, and provided with a flaring ange,

I, so that by lowering the delector, the thin 6o film of milk will be prevented from unduly spreading and be directed into the can, and be protected from the windwhen occasion may require. 1

I claim as my invention 65 A milk purifier, comprising a vessel, A, supported above a milk receptacle, said Vessel, A, having a strainer, B, therein covering the outlet, a neck, C, ixedly secured to the exterior of the vessel,'A, a disk, D, xedly sus- 7o pended from and offset from said neck, and the adjustable deflector, H, substantially as shown and described and for the purpose specified. e

In testimony whereof I aix my signature in the presence of the two undersigned Witnesses.

RICHARD H. CAsswELL.
